The Schrieffer-Wolff transformation, the Bogoliubov transformation, and the Green-function technique are applied as methods.\n\nIn part II models for high-Tc superconductivity (HTSC) in cuprates are investigated. In 1986 HTSC for La2−x Bax CuO4 , with Tc = 30 K at x = 0.2, was demonstrated for the first time by Bednorz and Müller. Based on the experimental background up to 1992 the Emery model and the Anderson-lattice model play a fundamental role at the theoretical description. The system of itinerant O(p) holes and localized Cu(d) spins is used to deduce the so-called t–J or p–d models. Here the tpp − Jpd − Jdd model is derived. There appears a competition between antiferromagnetism and possible HTSC.\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783960237204\"\u003e\u003ch3\u003eLecture Notes in Theoretical Physics\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9783960237204","offer_id":58186452369733,"sku":"9783960237204","price":32.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/c75da020-629f-4fdd-8617-a288fef2ac04.jpg?v=1781762082","url":"https:\/\/shop.autorenwelt.de\/products\/microscopic-concepts-of-superconductivity-von-edeltraud-kolley-und-winfried-kolley","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
